If the problem was with the cartridge - why wouldn't that problem be recognized? &nbsp;Thank you -</P> Sun, 22 Mar 2015 21:41:46 GMT https://community.usa.canon.com/t5/Desktop-Inkjet-Printers/Doe-Not-Print/m-p/136402#M5269 rosie46 2015-03-22T21:41:46Z https://community.usa.canon.com/t5/Desktop-Inkjet-Printers/Doe-Not-Print/m-p/136406#M5270 <P>I am replying to my own post. &nbsp;It appears that the knock off ink is just fine. &nbsp;The printer erroneously did not report that the ink level was too low on my large black cartridge. &nbsp;Fixed!</P> Sun, 22 Mar 2015 22:42:06 GMT https://community.usa.canon.com/t5/Desktop-Inkjet-Printers/Doe-Not-Print/m-p/136406#M5270 rosie46 2015-03-22T22:42:06Z
